CVE-2022-35845

Authenticated shell command execution via unneutralized input

Published Jan 3, 2023 · Updated Oct 23, 2024

OS command injection in Fortinet FortiTester 7.1.0, 7.0, 4.0.0 through 4.2.0, and 2.3.0 through 3.9.1 allows attackers to run shell commands. Fortinet reports multiple failures to neutralize special elements before attacker-controlled input reaches the underlying shell, but does not identify the affected commands or parameters. Authenticated product access is required; successful exploitation permits arbitrary commands with the appliance shell's privileges.
